Vitamins And Minerals: Vitamin A

Vitamin A is a fat-soluble vitamin essential for vision, immune function, and cell growth. It is found naturally in foods like liver, fish oils, eggs, and dairy products. It can also be added to foods or taken as a supplement, and is synthesized for food fortification.

Vitamin A is added to foods as a nutrient to help consumers meet their daily requirements. It is commonly found in fortified products such as breakfast cereals, milk, and infant formula.

Vitamin A is recognized as essential for health. The U.S. National Academies of Sciences, Engineering, and Medicine have established a Tolerable Upper Intake Level (UL) for vitamin A. International bodies like JECFA and EFSA have also evaluated vitamin A. Excessive intake of preformed vitamin A can be toxic, while deficiency can lead to vision problems and impaired immunity.
